Description

I am trying to get Native AOT build working with NET 8 RC2 and run into the following situation:

Assembly.GetCallingAssembly() throws System.PlatformNotSupportedException: Operation is not supported on this platform.

Once I tracked it down to this it became apparent that this is due to self-contained file not having calling assembly per se, which is fine, but it would have been VERY helpful if compiler/linker produced IL2026-like warning that this usage will fail, right now there is none, so that took extra time to locate what was going on. IL2026 warnings are very helpful pointing out likely issues for Native AOT builds and this instance deserves to be added to the list.

It's possible there are other similar exceptions that would deserve similar warning for Native AOT or even just self-contained builds.

Reproduction Steps

// Native AOT build -

Assembly.GetCallingAssembly();

Expected behavior

I expected to see IL2026-like warning from compiler, maybe even elevated to error that needs to be actively supressed if user desires so.

Actual behavior

No warning during compile/link time.

Regression?

No
